C:\Qt\Qt6.6\6.6.1\msvc2019_64\include\QtCore\qchar.h(85,5): error C2535: 'QChar::QChar(ushort) noexcept': member function already defined or declared!

/Zc:wchar_t vs. /Zc:wchar_t- I tried to fix it because there was an issue in this part, but it didn't work out. What should I do about this part? Please give me some advice.
